Wall, who has a lifetime scholarship to Kentucky, indicated he has already been looking ahead to life after basketball.

"I know you're proud of the man I've become," he wrote. "I'm the first in our family to attend college, and although I have not yet completed my degree, it is a goal that I hope to accomplish. My sister followed behind to become the first in our family to graduate from college and went on to get her master's."

Wall said he's unsure what he'll do with the business degree after the NBA, but he wants to be prepared for whatever life brings him.

"When our career is over, when we retire and the basketball stops bouncing, we still have to find something else to do," Wall said, per The Post. "Whether you want to be a general manager, a doctor, a businessman, whatever, you have to believe on everything you stand on."
